New Delhi, Nov 29: Delhi’s air pollution crisis shows no signs of abating, with the city recording an Air Quality Index (AQI) of 338 at 7 a.m. on Saturday, marking the 15th consecutive day in the “very poor” category. Health experts are warning that temporary measures alone will not suffice, stressing the urgent need for year-round solutions.
“We have reached an emergency in Delhi. Efforts to curb pollution cannot be only temporary; long-term strategies are urgently required,” said Dr. Anant Mohan, Head of Pulmonary Medicine and Sleep Disorders at AIIMS. He added that immediate action is needed to address the worsening situation.
Delhi’s 24-hour average AQI on Friday stood at 369, reflecting sustained poor air quality through half the month. Forecasts suggest little improvement in the coming week due to unfavourable meteorological conditions that prevent pollutant dispersion.
Dr. Saurabh Mittal from AIIMS highlighted that air quality issues are not limited to winter months. “Even in summer, the air remains suboptimal compared to global standards. Solutions must be implemented for the entire year, not just for short periods,” he said.
Experts cite both geographical and human factors as drivers of Delhi’s pollution. Gautam Menon, Dean of Research at Ashoka University, explained, “The Indo-Gangetic plains trap pollutants during winter when winds slow. This is worsened by vehicle emissions, biomass burning, unlicensed factories, festival fires, and constant construction.”
Air pollution poses serious short- and long-term health risks. Short-term effects include coughing, eye irritation, headaches, and asthma attacks. Long-term exposure can lead to chronic respiratory diseases such as COPD and lung cancer, cardiovascular problems, strokes, nervous system damage, and developmental issues in children.
“Particulate matter (PM 2.5) enters the bloodstream through the lungs, damaging blood vessels and raising blood pressure, which is a major contributor to strokes,” said neurologist Dr. P. N. Renjen.
Experts advise residents to wear masks during peak pollution hours and avoid early morning outdoor activities to minimise health risks.
